74HCT132N,652

Overview

The NXP USA Inc. 74HCT132N,652 is a high-speed Si-gate CMOS quad 2-input NAND gate with Schmitt trigger inputs, compliant with JEDEC standard No. 7A and pin-compatible with Low-power Schottky TTL (LSTTL). It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features reduced input threshold levels for TTL logic interfacing and includes clamp diodes on inputs to allow current limiting resistors for voltages exceeding VCC. Propagation delay is specified at 33 ns maximum at 4.5 V with a 50 pF load.

Feature Summary

• Schmitt trigger inputs transform slowly changing signals into sharply defined jitter-free outputs
• ESD protection exceeds 2000 V per JESD22-A114F (HBM) and 200 V per JESD22-A115-A (MM)
• Reduced input threshold levels enable direct interfacing to TTL logic levels
• Input clamp diodes facilitate connection to voltages in excess of VCC using current limiting resistors

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix '652' against the manufacturer's latest documentation to confirm package type and temperature grade alignment. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee authenticity. Cross-reference the part number with the official NXP Semiconductors database to validate current production status and any potential obsolescence notices before finalizing orders.

Selection Notes

Select this component when TTL logic level compatibility is required alongside Schmitt trigger noise immunity. The HCT logic family ensures proper voltage thresholds for interfacing with standard TTL systems while maintaining CMOS power efficiency. Verify that the operating environment falls within the specified -40 °C to +125 °C range and that the supply voltage remains between 4.5 V and 5.5 V for optimal performance.

Part Context

This device belongs to the 74HC/HCT series of high-speed silicon-gate CMOS logic components manufactured by NXP Semiconductors. The series is designed to be pin-compatible with Low-power Schottky TTL (LSTTL), facilitating easy upgrades or replacements in existing designs. The 74HCT variant specifically targets applications requiring TTL-compatible input voltage levels while offering the benefits of CMOS technology.

Replacement Considerations

The 74HC132N serves as a functional alternative within the same family, though it requires different supply voltage considerations compared to the HCT version.
